Is support for then-able values on the roadmap for handsontable? If not, is it the sort of thing that would be a feasible pull request? It seems like it’s not a super complicated change to the existing editors that I could make myself, but I don’t know if there are other considerations I’m not aware of.
I greatly appreciate your feedback. We’re planning to refactor editors but there’s not a deadline for this task yet.
We always appreciate pull requests but at this point we do not know how the structure of editors would look like after they’ll be refactored. I’ll save your topic as a feature. Idea of a Promise object sounds usefull and I hope we could get back to it after the above task is completed.
